routing workshop under A In our first issue of INProfile (Issue 1 Winter 1997 pages 22-25 ) we featured a dedicated routing bench, that could be easily made in the workshop and that would form a routing centre to support a wide range of routing operations. In this issue we suggest ways of incorporating both inverted and overhead routing facilities in the same routing centre. One of the many benefits afforded by making your own routing bench, is that it can be of a size to suit both one’s own requirements and the available floor 26 INProfile over John Perkins adds an additional feature, in the form of an inverted router table, to his dedicated routing bench. by John Perkins n inverted or overhead table is one of the most important accessories for the router, offering far greater scope in handling material, as well as giving the full range of router cutters. It is also by far easier and safer to carry out many routing operations with the router rigidly mounted and by feeding the material into the cutter, against a fence and on a flat table. Also, as the table, cutter and fence will always remain square to each other, accuracy can be assured. and space. Inverted routing When making any routing jig or table it is important to keep it simple, both in its construction and its use. For simplicity and reliability, it is worth considering using proprietary products such as those from the Trend range of jig-making accessories. These include mounting plates, threaded inserts, lever handles and knobs, and items from their Routerack Range. A bonus is that the Routerack universal stand set offers many possibilities for mounting the router over the bench. Plates can be made from various materials such as polycarbonate sheet, aluminium or solid plastic. Here the Trend CRT plate is set into a thicker table plate to allow the router to be lifted through the table. Bench cut-out Mounting the router One of the main problems in constructing any routing table is in the method of attaching the router, to both ensure that it is secure and rigid and to minimise the loss in the depth of cut due to the thickness of the mounting plate. Mounting plates There are various methods of making mounting plates, although it is often better to buy ready drilled plates such as the CRT insert plate. This is available pre-drilled to suit most popular routers. For ease of fitting and cutter changing, the table aperture should ideally be large enough to allow the router to pass through. On 6mm MDF or plywood, mark out a rectangle equal in size to the mounting plate. Draw a line 12mm in from the edges of the rectangle and cut out to form a template. Position this template on the bench centring it across the top and square to the front edge. With a jigsaw cut out the central portion leaving a 1.5mm gap to the inside line. Use a bearing guided straight flute cutter to trim the edge, whilst following the template and a 12mm bearing rebate cutter to form a rebate around the cut-out equal in depth to the thickness of the plate. Check that the plate fits, trimming the edge of the rebate to form a sliding fit with no side movement. Fit the router plate and check that it is level with the bench surface. If preferred, cut the rebate slightly deeper and either apply metal or plastic shims to the rebate face, or use adjustable screws as supplied in Autumn 1998
